Enter the change in shock position (in) and the change in wheel position (in) into the Motion Ratio Calculator. The calculator will evaluate and display the Motion Ratio. 

Motion Ratio Formula

The following formula is used to calculate the Motion Ratio. 

MR = dS / dW

  • Where MR is the Motion Ratio ( )
  • dS is the change in shock position (in) 
  • dW is the change in wheel position (in) 

How to Calculate Motion Ratio?

The following example problems outline how to calculate Motion Ratio.

Example Problem #1:

  1. First, determine the change in shock position (in). 
    • The change in shock position (in) is given as: 2.5.
  2. Next, determine the change in wheel position (in). 
    • The change in wheel position (in) is provided as: 4.
  3. Finally, calculate the Motion Ratio using the equation above: 

MR = dS / dW

The values given above are inserted into the equation below and the solution is calculated:

MR = 2.5 / 4 = .625

Example Problem #2: 

For this problem, the variables required are provided below:

change in shock position (in) = 4.5

change in wheel position (in) = 7

Test your knowledge using the equation and check your answer with the calculator above.

MR = dS / dW = ?
